This invention. relates to. an improved strike foruse on doorxjarnbs in cooperation with door locks and to a die forproducing the same.

Many situations arise wherein the space be tween a door jamb and its door is such that the bolt or latchof the door lock as mounted on the door is incapableof reaching the strike so as to be engageable therewith toretain the door :in closed position. These situations arise from a number of different circumstances such as, for example, the settling of the building in which the door jamb is'located, the shrinkage of the door and, in some instances, the'initial fitting of the door and door jamb has been improperly performed. In many instances of wartime housing where green or insu-fiiciently driedlumber was employed the shrinkage of the door and-of the door Jamie and the Warping of these elements on drying has caused the space between the edge of the door and the side of the door jamb to open to such extent that the latch or bolt of the door look, even in its fully extended position, will not quite engage the strike.

An object of the present invention is to provide an improved strike which differs from the conventional strike in that a bulge or protuberance is formed adjacent the locking edge of the strike so that this edge will be causedto extend toward the edge of the door and thus'be engageable by the end'jof the bolt or latch of the door lock; As the strike is made of malleablemetal this protuberance or bulge may be utilized or not; depending upon the circumstances of the particularcdoor and door jamb in question and, =if the edge'of the door is sufficiently close to the door jamb so that the bulge or protuberance need not be used, the strike may be readily flattened adjacent its locking edge to conform to the conventional strike.

Another object of the invention is to provide a very simple die which may be utilized advantageously to form strikes embodying the present invention or which may be utilized to deform or modify a conventional strike so as to extend its locking edge toward the edge of the door and thus enable the bolt or latch f the door lock to engage it when the spacing between the door edge and the iamb is found to be too great.

With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is an exploded view of the die emstrike illustrating the l 2 clams- [(cl. eta-e40) bodying the present invention and illustrating conventional'strike as about to be positioned" therein to be deformed in accordance with the present invention; 7 l i Fig. 2 is a vertical section through the die and strike as being deformed b-ythedie; i

Fig. 3 is a perspective view of a strike embodying the present invention; and J 1 4 is a perspective view illustrating the strike as shown in Fig. 3 as being returned to the shape of a conventional strike when the deformed locking edge thereof is not required-m I; L"

Referring to the y accompanying drawings wherein similar reference characters designate similar parts throughouirlfl indicates a conventional strike for 'doorlocks consisting of a section of heavy sheetmetal, usually generally rectangular in form, and having apertures H for the reception of screws'by: whichethe strike is at-.

tached to the janib. Near-the centerof the sec-+ tion there is a rectangular aperture I Zof-such size and-shapeas to receive the latch or bolt of the. door lock with which the strikeis associated. Along one edge of the section there is a laterally bent lip [3 which presents outwardly'a convex surfacemerging smoothly into thesurfaceof the strike and whichis engageableby the bolt or situation I provide a die consisting of a female member 15 the top surface of which is fiat complementary to the face of the body of the strike I8. Along one side the top surface of the female member is curved upwardly as indicated at H? complementary to the underside of the upwardly curved lip It so that when the strike I0 is positioned thereon it will rest evenly on the female A member. An aperture I! is formed in the female member at such a position to register with the aperture l2 in the strike. On the other side of the female member there is formed a concavity ber of the die, indicated at l9, has at its lower end a guide 20 of such size and shape as to be receivable through the aperture I 2 and in aperture ll of the female die. This male member presents a. convex under surface 2| complementary to the concave surface [8, and extending laterally from the side of the guide 20.

When it is desired to deform a conventional strike to produce a strike in accordance with the presentinvention, ,the conventional strike is positioned "on thefemale die and the guide 28 extended therethrough into the aperture ll. The male member of the die is then forced downwardly such as by a hammer blow into the position shown in Fig. 2, thus deforming the strike along the locking edge I4 by forcingthemetal thereof downwardly into the concavity I8. Thus the completed strike as shown in Fig. 3

presents a concave surface 22 along the locking edge M on that side of the strike toward which the lip i3 is bent. On the opposite side of the strike there will be a corresponding bulge or protuberance .orembossment indicated at 23. In

thief-manner. the locking edge M will be pro-- jectedioutwardly fromJthe: plane of the body of the strike in a direction opposite that from which.

without springing back. The strike-thus'produced or" deformed can frequentlybe used to advantage as. the projectionof the locking edge I4 is frequently sufficient to have the bolt engage it to hold the door in closed position.

It is contemplated within the scope of the invention to distribute-as a manufactured ar-' ticle strikes as illustrated in Fig. 3. However, in many instances the fit between the door and the door jamb is such that the protuberance or embossment at 23 is not necessary and may be undesirable. In such an event the improved strike may be positioned on a flat 'anvil 24 and the metal at the-protuberance flattened out such as by 'a' hammer H, as shown in Fig. 4, thus returning the strike from the position shown in Fig. 3- tothe form of a conventional strike as shown'in Fig; 1;

From the above described construction it will be appreciated that an improved strike has been provided which may be advantageously employed in many situations wherein the strike as mounted on a door jamb is located too remote from the door lock as mounted on the door. Also, a die for producing the same has been provided'thatmay be conveniently-carried and utilized by carpenters to modify or deform conventional strikes to produce strikes embodying the present invention.

Various changes may be made in the details of construction without departing from the spirit and scope of the-invention as defined by the appended. claims.

I claim:

1. A strike-fordoor locks comprising a section of sheet metal having an aperture therethrough adapted to receive a bolt of a door lock and having a laterally bent lip along one edge engageable by the bolt in the course .of the closing of the 'door on which 'thelock' is'mountedto force; the bolt into :retracted positionfrom' whichrit may enter the aperture, the .metal .of-ithestrike adjacent the edge of the aperture; which is mostadjacent the lip beingbent out iof-the planeiof said section in the opposite directionzfromt that in which the lip is-bent.

2. A strike for door locks-comprising a section of sheet metal having an aperture therethrough: adapted to receive the bolt of a door lock-and:

one edge of which serves asa locking edgeene gageable by the bolt, the metal of the strike' along said edge beingbent outwardly out of the plane of thestrike so as to extend towardlthe edge of the door with-whose door lock the strike is adapted'to be associated;
